3856633 ÷ 809 
We want to figure out the number of times 3856633 can be divided by 809.

On to step 1:
When dividing 3 by 809, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 809

On to step 2:
The number 809 fits into 38 0 times, leaving a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Fetch the next digit (5) from the dividend, attach it to 38 and continue: 385 / 809

Let's proceed to step 3:
When dividing 385 by 809, we get 0 with a remainder of 385.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 385 to get 385.
Grab the next digit (6) from the dividend, add it to 385, then carry on: 3856 / 809

Step 4:
809 can be fit into 3856 4 times, resulting in a remainder of 620.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
The remainder is 620 after subtracting 3236 from 3856.
Append the next digit (6) from the dividend to 620 and continue with: 6206 / 809

Let's proceed to step 5:
6206 divided by 809 is 7 with a remainder of 543.
Put 7 as the next digit of the answer. 
Result so far: 47.0
If we take 5663 away from 6206, we end up with 543.
Append the next digit (3) from the dividend to 543 and continue with: 5433 / 809

Step 6:
809 goes into 5433 6 times with a remainder of 579.
The next digit of our result is 6. 
Result so far: 476.0
Subtract 4854 from 5433 to get 579.
Append the next digit (3) from the dividend to 579 and continue with: 5793 / 809

Let's proceed to step 7:
If we divide 5793 by 809, we get 7 and a remainder of 130.
Put 7 as the next digit of the answer. 
Result so far: 4767.0
Subtract 5663 from 5793 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 8:
The number 809 fits into 1300 1 times, leaving a remainder of 491.
Use 1 as the next digit of our solution. 
Result so far: 4767.1
Deduct 809 from 1300 and we're left with 491.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4910, and continue the process.

On to step 9:
When dividing 4910 by 809, we get 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 4767.16
If we subtract 4854 from 4910, we get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

On to step 10:
When dividing 560 by 809, we get 0 with a remainder of 560.
The next digit of our result is 0. 
Result so far: 4767.16
Deduct 0 from 560 and we're left with 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

Advancing to step 11:
5600 divided by 809 is 6 with a remainder of 746.
Write down 6 as next digit of the result. 
Result so far: 4767.1606
If we take 4854 away from 5600, we end up with 746.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7460, and continue the process.

On to step 12:
If we divide 7460 by 809, we get 9 and a remainder of 179.
Write down 9 as next digit of the result. 
Result so far: 4767.16069
Subtract 7281 from 7460 to get 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

Moving on to step 13:
809 goes into 1790 2 times with a remainder of 172.
Put 2 as the next digit of the answer. 
Result so far: 4767.160692
Deduct 1618 from 1790 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

On to step 14:
1720 divided by 809 is 2 with a remainder of 102.
Record the quotient 2 as the next digit in the result. 
Result so far: 4767.1606922
Deduct 1618 from 1720 and we're left with 102.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1020, and continue the process.

After the division, we end up with 4767.1606922 and a remainder of 1.02e-06.
